GENERAL INSTRUCTIONS FOR 230V MACHINES

The following will enable you to observe good working
practices, keep yourself and fellow workers safe and
maintain your tools and equipment in good working
order.

WARNING!! KEEP TOOLS AND
EQUIPMENT OUT OF REACH
OF YOUNG CHILDREN

KEEP WORK AREA AS
UNCLUTTERED AS IS PRACTICAL
UNDER NO CIRCUMSTANCES
SHOULD CHILDREN BE ALLOWED
IN WORK AREAS.

Mains Powered Tools

• Tools are supplied with an attached 13 Amp UK 3 pin

plug, fitted with 5 amp fuse

• Inspect the cable and plug to ensure that neither are
damaged. Repair if necessary by a suitably
qualified person.

• Do not use when or where it is liable to get wet.

Workplace

• Do not use 230V a.c. powered tools anywhere

within a site area that is flooded.

• Keep machine clean.

• Leave machine unplugged until work is about to

commence.

• Always disconnect by pulling on the plug body
and not the cable.

• Carry out a final check e.g. check the cutting tool

is securely tightened in the machine and the
correct speed and function set.

• Ensure you are comfortable before you start work,

balanced, not reaching etc.

• Wear appropriate safety clothing, goggles, gloves,
masks etc. Wear ear defenders at all times.

• If you have long hair wear a hair net or helmet to
prevent it being caught up in the rotating parts of the
machine.

• Consideration should be given to the removal of rings
and wristwatches.

• Consideration should also be given to non-slip

footwear etc.

• If another person is to use the machine, ensure they
are suitably qualified to use it.

• Do not use the machine if you are tired or distracted.

• Do not use this machine within the designated safety

areas of flammable liquid stores or in areas where
there may be volatile gases.

• Check cutters are correct type and size, are
undamaged and are kept clean and sharp, this will
maintain their operating performance and lessen the
loading on the machine.

• OBSERVE…. make sure you know what is
happening around you and USE YOUR COMMON
SENSE.

SPECIFIC SAFETY PRECAUTIONS FOR GRINDING MACHINES

1. Do not operate your machine until it is completely

assembled and installed according to the instructions.

2. If you are not familiar with the operation of
grinding machines obtain advice from your supervisor
or instructor or another qualified person.

3. Only use grinding wheels or attachments rated
higher than 3600 rpm with a 5/8”(16mm) arbor on this
machine.

4. Never use a chipped or cracked wheel. Always
inspect each wheel before mounting it on the grinder.
If during inspection you discover a damaged grinding
wheel, replace it immediately.

5. Do not over tighten wheel nuts.

6. Always maintain a distance of 2mm or less between

the wheel and the tool rest. Adjust the tool rests as the
wheels decrease in size.

7. Ensure the tool rests are tightened so they cannot

move while in use.

8. Never grind on a cold wheel. The grinder should

always be run for at least one minute before applying
work to it.

9. Never grind on the side of the wheel. Always grind

on the face of the wheel only.

10. Never apply coolant directly to a grinding wheel,

it may cause the bonding to fail. If the work piece be­comes hot, dip it into a water pot to cool it down.

11. Hot sparks are a hazard! Never carry out grinding

operations near flammable gas or liquid.

SPECIFIC SAFETY PRECAUTIONS FOR GRINDING MACHINES

12. Always make sure the spark guards and eye shields

are in place, that they are properly adjusted and
secured.

13. Keep the spark guards close to the wheels and
re-adjust them as the wheels wear.

14. Ensure the soft washer and the flanges furnished
with the grinder are used to mount any attachments
(grinding wheels, wire brushes, buffing wheels, etc)
onto the shaft.

15. Always stand to one side of the grinder when
starting the machine.

16. Avoid awkward hand positions where a sudden slip

could cause the hands to come into contact with a
grinding wheel, wire brush etc.

17. If the wheel requires dressing, dress only the front

of the wheel, do not dress the sides.

18. Do not use any attachments that causes the

machine to vibrate. If, after changing grinding wheels
or adding attachments, the machine does vibrate,
remove the recently replaced item and change again.

19. Grinding creates heat. Do not touch the work face

of the work piece until you are sure it has cooled down
sufficiently.

SPECIFICATION

SETTING UP THE GRINDER

Place the grinder on a flat level surface. There are two
machined slots to either side of the grinder housing to
bolt the machine onto a work bench if required, see
fig 01.

Adjust the two tool rests leaving a gap of approximately

1.5mm clearance between the grinding stone and the
tool rest, see fig 02

Step 1-2

CONNECT THE GRINDER
TO THE MAINS SUPPLY.

ALWAYS WEAR EAR
DEFENDERS AND SAFETY
GOGGLES.

CHANGING THE GRINDING STONE

DISCONNECT THE GRINDER
FROM THE MAINS SUPPLY.

SETTING UP THE GRINDER

Carry out final checks e.g. check the gap between the
tool rest and the stone is correct, check the stone is
not badly deformed (rounded edges, grooved face, etc;
unless you have specifically shaped the stone to these
profiles), check the eye shield is correctly positioned.
Have a cooling pot to hand if you need it. Start the
machine, wait until it reaches full speed. Check it runs
smoothly, no knocking or scraping noises for example.
If all ok, switch off the grinder and wait until it comes
to a complete stop. Disconnect the machine from the
mains supply.

Step 3

Unscrew the three screws from the inner guard and
remove the outer stone guard cover. Place safely to
one side.

Grasp the stone using a cloth, use a 19mm spanner
to loosen the nut, remember undo the nut in the
direction of the stone’s rotation as indicated by the
arrow on the guard cover.

Step 4

CHANGING THE GRINDING STONE

Step 5-6

Remove plate flange and carefully remove the stone.
Clean the interior stone guard, inspect the new stone
for cracks and damage to either the front face or the
edges before fitting. Carefully slide the stone on the
shaft, replace the plate flange, the nut and tighten
against the rotation of the stone. DO NOT

OVERTIGHTEN.

Step 8-9-10

Step 7

CONNECT THE GRINDER
TO THE MAINS SUPPLY.

Reconnect the grinder to the mains supply, give the
grinder a ‘short burst’, by switching it on and off
quickly. Check the grinder is not subject to any
undue vibration. If the grinder does vibrate, switch off
immediately and disconnect from the mains supply.
Remove the guard cover and check stone and plate
flange is fitted correctly. Check again, if the grinder
is still vibrating the stone/s may need dressing. Dress
the new stone lightly to ensure a ‘good face’ and good
concentricity.

10

DRESSING THE STONECHANGING THE LIGHT BULB

CONNECT THE GRINDER
TO THE MAINS SUPPLY.

Switch on the grinder, wait until it reaches full speed
and leave the machine running for at least one minute
before carrying out any work. Apply a work piece and
check that the spark guard is correctly positioned and
that the tool rest is securely fixed. Switch off and wait
until the grinder comes to a complete stop.

DISCONNECT THE GRINDER
FROM THE MAINS SUPPLY.

After a period of time uneven wear on the stones
including crests dips or rounded edges will appear.
They will need to be dressed out using a suitable wheel
dressing stick. See our website and in our catalogue for
details, see fig 10-11.

Fig 10-11

Code 410074

CONNECT THE GRINDER
TO THE MAINS SUPPLY.

Switch the grinder on and allow it to run for at least
one minute. Rest the dressing tool on the tool rest and
advance it to the stone until it touches the maximum

Fig 12

diameter; gently move the dresser back and forth
across the face of the stone until all irregularities have
been removed and the edges of the stone are nice and
sharp, see fig 12.

Changing the Light Bulb

Step 13-14

Wheel Dressing Stick for coarse carborundum
and dressing worn or unbalanced wheels.

Code 410057

Diamond Dressing Block useful for dressing across
the width of the grinding wheels or to produce flatter
surfaces than single point dressers.

The flexible light has a 12V 0.36W screw threaded LED
bulb. Unscrew the blown bulb and replace.
